CSP4

PROCESSOR
Intel® Pentium® 4 processor at speeds of 2.0GHz to 3.0GHz
Intel® Celeron® processor at speeds of 2.0GHz to 2.5GHz

CHIPSET
The CSP4 uses Intel® 875P chipset featuring Intel® Performance Acceleration Technology (Intel® PAT). Intel® PAT provides a faster path between the processor cache memory and DDR system memory that increases overall system performance while taking full advantage of the new Intel® Pentium® 4 processor's 800MHz Front Side Bus (FSB). The CSP4 features a dual channel DDR266/333/400 memory interface, 400MHz, 533MHz or 800MHz FSB support, an AGP 3.0 video interface with 4x data transfers and dual Serial ATA/150 ports. Additional chipset capabilities include USB 2.0, PCI-X/PCI, Ultra ATA/100, Intel® Communications Streaming Architecture (CSA) support for direct-connect Gigabit Ethernet and a 266MB/s Hub Interface to Intel's E6300ESB I/O Controller Hub.

BUS SPEED
ISA* 16-bit/8MHz
PCI 32-bit/33MHz, 32-bit/66MHz

System or FSB 400MHz, 533MHz or 800MHz
*Contact Core for details on the CSP4's ISA implementation.

BIOS (FLASH)
The CSP4 uses AMIBIOS8®. The flash BIOS resides in the 82802AC Firmware Hub (FWH). AMIBIOS8 contains features such as:
Support for flash devices for BIOS upgrading via floppy interface
Integrated support for USB mass storage devices such as USB CD-ROM, CD-RW, etc.
Boot from network, USB mass storage devices, IDE or ATAPI
Serial port console redirection to support headless operation
SATA/ATA/ATAPI support includes 48-bit LBA addressing to support SATA/ATA/IDE hard drive capacities over 137GB

CACHE MEMORY (L2 AND L1)
The Intel® Pentium® 4 processor's level two (L2) cache memory is an integrated on-die Advanced Transfer Cache memory that is 8-way set associative and runs at the full processor core frequency. Processor options are available that provide either a 512K or 1M L2 cache memory. Intel® Celeron® processors have a 128K L2 cache.

All processors have a 12K L1 Execution Trace Cache. Processors which have 1M of L2 cache memory have a 16K data cache; all other processors have an 8K data cache.

DDR266/333/400 MEMORY
The two DIMM sockets on the CSP4 support a total memory capacity of 2GB. The 875P has an Intelligent Memory Manager feature that automatically detects the speed and placement of the DDR DIMMs and applies the appropriate memory frequency and speed to the DDR266/333/400 interface. The interface can operate as either a single-channel or dual-channel DDR interface. With one DIMM installed, the interface operates as a single-channel interface supporting a PC2100, PC2700 or PC3200 unbuffered 184-pin ECC or non-ECC DDR DIMM. Installing one DIMM produces an interface bandwidth of either 2.1GB/s, 2.7GB/s or 3.2GB/s. Dual-channel DDR interface operation occurs by installing two identical DIMMs, which doubles the interface bandwidth to 4.2GB/s, 5.4GB/s or 6.4GB/s.

PCI-X/PCI BUS INTERFACE
The CSP4's 32/64-bit PCI-X/PCI bus interface connects from the SBC's I/O Controller Hub directly to the backplane and is capable of running at a 33MHz or 66MHz bus speed.

An additional PCI Local bus, which runs at 32-bit/33MHz, supports one of the board's 10/100/1000Base-T Ethernet controllers and the optional Ultra160 SCSI controller.

ISA BUS INTERFACE
The CSP4's ISA bus interface supports legacy ISA slots, with the following limitations: ISA Bus Mastering, 16-bit I/O and 16-bit memory accesses are not supported. When a 16-bit access is executed to the CSP4's ISA bus, the transfer will be divided into two 8-bit accesses. If the ISA option card being used only operates in word, i.e.16-bit, mode, transfer data will be missed. If the ISA option card supports both byte, i.e. 8-bit, mode and word mode, the data transfer will be correct, but throughput performance will be reduced.

DUAL EIDE ULTRA ATA/100 INTERFACES
Dual high performance PCI Bus Master EIDE interfaces are capable of supporting up to two IDE disk drives each in a master/slave configuration. Supports Ultra ATA/100 with synchronous ATA mode transfers up to 100MB per second.

DUAL USB INTERFACES
The CSP4 supports two high-speed USB 2.0 ports for data transfers up to 480Mbit/sec. It also supports USB 1.1 devices for data transfers at 12 or 1.5Mbit/sec. The Universal Serial Bus (USB) is an interface allowing for connectivity to many standard PC peripherals via an external port.

SYSTEM HARDWARE MONITOR
The Winbond W83783S chip supports hardware monitoring. The functions monitored are voltage (+2.5V, +3.3V, +/-12V, +5V and VCORE), fan speed and temperature. The CSP4 hardware monitor driver allows the user to program the monitor limits to provide a trigger point for the application software. The user's application program can monitor these trigger points in order to send system alert messages or perform corrective actions.

DUAL ETHERNET INTERFACES - 10/100/1000BASE-T
The CSP4's Gigabit Ethernet Controller (Intel 82547GI) uses the new Communication Streaming Architecture (CSA) feature on the 875P MCH to provide a high-speed 10/100/1000Base-T Ethernet interface. Connecting directly to the MCH via CSA approximately doubles the peak available bandwidth and provides a low-latency path to memory that increases network performance. The second 10/100/1000Base-T Ethernet interface is provided by the Intel 82540 PCI-based controller. RJ-45 connectors, located on the I/O bracket, provide the physical interface to the Ethernet network.

DUAL SERIAL ATA/150 PORTS
The primary and secondary Serial ATA (SATA) ports on the MX8 comply with the SATA 1.0 specification and support two independent SATA storage devices such as hard disks and CD-RW devices. SATA technology provides lower pin counts, reduced signaling voltages, simplified cabling, CRC error detection and hot-plug support. SATA produces higher performance interfacing by providing data transfer rates up to 150MB per second on each port.

ULTRA XGA VIDEO INTERFACE
The ATI® M6-C16H video controller enables 2D/3D video acceleration and provides 16MB of integrated video DDR memory. The video controller supports pixel resolutions up to 1600 x 1200 (UXGA). Software drivers are available for most popular operating systems.

ULTRA160 SCSI INTERFACE (OPTIONAL)
The Ultra160 SCSI interface uses an Adaptec AIC-7892 SCSI controller chip and supports SCSI device data transfer operations up to 160MB/s. The interface supports up to 15 SCSI devices, complies with the SPI-3 standard and is compatible with both single-ended and Low Voltage Differential (LVD) SCSI I/O. Software drivers are available for most popular operating systems.

SERIAL INTERFACE
The Super I/O controller supports two full-function serial ports with independently programmable baud rates. The controller has two high-speed, NS16C550 compatible UARTs with Send/Receive 16-byte FIFOs. The IRQ for each serial port has BIOS selectable addressing.

FLOPPY DRIVE INTERFACE ENHANCED BI-DIRECTIONAL PARALLEL INTERFACE
The parallel port interface is compatible with IBM PC/XT®, PC/AT®, PS/2TM, Enhanced Parallel Port (EPP1.7, EPP1.9) and Extended Capabilities Port (ECP) modes of operation. Both the EPP and ECP modes are IEEE 1284 compliant. The parallel port has BIOS selectable addressing.

WATCHDOG TIMER
The programmable watchdog timer is supported directly by the I/O Controller Hub. Two operating modes, free-running and one-shot, are available with this two-stage watchdog timer. Stage one can generate IRQ, SMI or SCI, and stage two generates a programable watchdog timer reset with a total range of 1ms to 10 minutes.

* From backplane via PICMG® connector.
** From ATX12V power supply or equivalent via P24 connector.

The processor's power requirements created the need for an additional on-board 4-pin power connector. This connector requires +12V from an external power supply that conforms to the ATX12V power specification.

This external power supply should have a wattage rating of at least 250W. The MX8 also requires that the power supply provide +3.3V to the backplane's processor slot.

The system power supply must conform to the power sequencing specifications of ATX compliant power supplies. Voltage levels must be regulated within a range of +/- 5%.

The high-performance Intel® Pentium® 4 processor used on the MX8 may consume over 100 Watts of power. The MX8's cooling system uses a high-reliability fan mounted to the SBC.

MECHANICAL
An active cooling system is used on the MX8 to insure reliable processor operation at elevated temperatures. Overall dimensions for the MX8, including the active cooling system, are 13.3" L (338mm) x 4.8" H (121.9mm) x 2.3" W (58.4mm).

SBCs with processor speeds greater than 2.8GHz use a taller active cooling system and have overall dimensions of 13.3"L (338mm) x 4.8"H (121.9mm) x t.bd"W(tb.dmm).

*Core validates extended temperature operation for processor speeds 2.8GHz and below using a 2.3" (58.4MM) tall active cooling system. There are exceptions at the 2.8GHz processor speed. Consult Core for details.
